Provided are integrated domestic
sewage treatment equipment and treatment method. The integrated domestic
sewage treatment equipment is formed by the following treatment units: a gridding
feces tank, an anaerobic tank, an aerobiotic tank and a precipitating and sterilization pond, all of which are sequentially communicated. The integrated domestic
sewage treatment equipment is characterized in that water inlet and outlet pipes are arranged between the treatment units, each
treatment unit is provided with a mud discharging
pipe and an exhausting
pipe, the anaerobic tank and the aerobiotic tank are each provided with an aerating
system and a flow-back
system, a triangular weir is adopted in water outflow of each
treatment unit, the input end of the water inlet
pipe of the gridding
feces tank is located outside the equipment, and an inlet penetrates into the portion, before a grid, at the bottom of the gridding
feces tank; the gridding feces tank is connected with the anaerobic tank, the water inlet pipe of the anaerobic tank is communicated with the interior of the bottom of the tank for water inflow, and a filling area of the anaerobic tank is filled with a fixed carrier and biological
sponge iron filler; the anaerobic tank is connected with the aerobiotic tank, the water inlet pipe of the aerobiotic tank is communicated with the bottom of the tank for water inflow, and a filling area of the aerobiotic tank is filled with a fixed carrier and biological
sponge iron filler; the aerobiotic tank is connected with the precipitating and sterilization pond, the water inlet pipe enters the middle of a precipitating pond body, and a 45-degree slope is arranged in a
sludge area at the bottom of the pond; the precipitating pond body is connected with a sterilization pond body, the water inlet pipe enters the bottom of the sterilization pond body for
chlorine tablet sterilization, and water is output out of the upper water outlet pipe.
